Tax Registration After Incorporating Your Company in Timor-Leste

Registering your company through SERVE is a milestone, but it is not the finish line. A newly registered company is a legal person that exists on paper. Before it can trade properly, it needs to register for tax and be set up to meet its obligations. This step is where many founders lose momentum, and where getting organised early pays off.

Here is what tax registration involves and how to start on the right foot.

Register for tax and get your TIN

Once your company is registered, the next move is to register it for tax with the tax authority and obtain a Taxpayer Identification Number, or TIN. The TIN is the company’s identity for everything tax related. You will use it to file returns, and it underpins how the company invoices customers and pays staff correctly.

Without a TIN, the company is not properly set up to operate. So treat tax registration as part of the same project as company registration, not as something to handle later. A clean setup has the company registered through SERVE and tax-registered with a TIN in hand, ready to trade.

When you register for tax, you are also identifying which taxes will apply to your business. That depends on what you do, so it is worth getting advice on your specific activity rather than assuming. The main obligations for most companies are described below.

Understand the monthly tax return

Tax in Timor-Leste runs on a monthly clock. From your first active month, the company files a monthly tax return. This is the single regular obligation that shapes your compliance rhythm, and building the habit early keeps it light.

The monthly tax return brings together the main taxes a typical company deals with:

Wage Income Tax applies at 10% on resident wages above $500 per month. If you employ staff, you withhold and account for this through the return.

Services Tax applies at 5% on monthly turnover above $500 for businesses in hospitality and telecom. If you are in one of those sectors, this is part of your monthly filing.

Withholding tax applies where relevant, for example on certain payments your company makes. Whether it applies depends on the nature of the payment, so this is an area worth checking carefully.

Note the house point: it is a monthly tax return, filed and paid each month. There is no annual scramble that substitutes for it. Once the routine is in place, reconcile, prepare, lodge and pay, it becomes light work. Without the routine, every month turns into a small emergency.

Set up your accounting to support it

Filing accurately each month is only realistic if your records keep pace. The companies that struggle are the ones that postpone their accounting and then try to rebuild several months of history from a drawer of receipts right before a deadline.

The better path is to stand up your accounting from day one. Put a proper ledger in place, connect your bank feeds, and use a sensible chart of accounts so every transaction is captured as it happens. We commonly set companies up on QuickBooks so the monthly return is a quick exercise drawn from clean records rather than a reconstruction.

Keep the company’s money separate from personal funds, retain your invoices and receipts, and run a monthly close. That discipline is what makes the monthly tax return a small, predictable task instead of a recurring source of stress.

Get the sequence right

The full setup sequence is simple when followed in order. Register the company through SERVE. Register for tax and obtain your TIN. Open the company bank account. Stand up your accounting. Then file your first monthly tax return from your first active month and keep the rhythm going.

Each step depends on the one before, so skipping ahead causes rework. Done in order, your company is properly established, compliant from the start, and free to focus on customers rather than catching up on paperwork.
